Error message: No trust relationship

Dear Team,
We were migrating active directory users and computers from win2k3(source) to win2k8(target).
After migrating a PC, the pc is not allowing to login with any user eithersourcer AD account or target AD Account.
it gives the below error:
"The Security database on the server does not have a computer account for this workstation trut relationship".

I'm sure this is too late to help you, but others may benefit. Unplug the network cable from the PC and logon with a previously used domain account and you will be able to logon with the cached credentials. Then plug the PC back into the network and remove/rejoin the domain.
